Method and apparatus embedding PCI-to PCI bridge functions in PCI devices using PCI configuration header type 0

摘要

A method and apparatus embedding PCI-to-PCI bridge functions in PCI devices using PCI configuration header type 0 is disclosed. The PCI-to-PCI bridge function is implemented in PCI devices using the standard Type 0 PCI Configuration Header that supports up to six Base Address Registers. Having the PCI-to-PCI bridge function integrated with other PCI device functions has the advantage of reducing valuable card real estate and power consumption.
